Ghana · MTN MoMo · Twi

Send mobile money by speaking Twi.

“Fa fifty cedis kɔma Ama.”
Send fifty cedis to Ama.

That sentence is the whole interaction. Vomo reads back who and how much, waits for one confirmation, then opens MTN’s *170# menu and types every step on your behalf — the recipient, the amount, the reference and the PIN.

Seven entries, one spoken sentence, no taps.

One sentence, one confirmation

Everything Vomo needs is decided before it dials. Once the menu opens there is no time to ask you anything.

  1. Wake it

    Say “Hey Vomo”, or tap Kasa. Vomo can also listen while it’s closed, so the phone never has to be unlocked and navigated first.

  2. Say what you want

    Speak naturally in Twi or English. Phone numbers go in one digit at a time, in either language, and you can take the last one back.

  3. Hear it back

    Vomo says the name and the amount out loud and shows them large on screen. If it wasn’t sure what it heard, it asks instead of guessing.

  4. Confirm once

    Say 1 to send or 2 to stop. This is the last checkpoint before money moves, so a spoken “1” needs higher confidence here than anywhere else.

  5. Vomo runs the menu

    About seven entries in roughly twenty seconds, with the progress read aloud. You end up on MTN’s own receipt — recipient, new balance, transaction ID.

Two ways to talk to Vomo

Set in Settings, under “How to talk to Vomo”. Both wake on the same phrase.

Twi

Answers are digits and aane / daabi, recognised by Vomo’s own on-device model. Nothing leaves the phone to understand them, so it works on a weak connection.

English

The same questions take ordinary answers — “check my balance”, “yes”. A phrase Vomo can’t use is asked again twice, then it goes back to waiting.

Phone numbers are the exception: in both modes Vomo’s own model hears the digits, with the microphone held open until all ten are in.

Built for the people USSD leaves out

MTN’s menu is English-only, text-heavy and on a timer. That is a poor fit for a lot of people who depend on it every day.

You don’t have to read

Audio is a first-class output, not an add-on. Every screen also works heard and through TalkBack, for people with low vision or limited literacy.

You don’t have to switch to English

Twi is the default, not a translation layer bolted on afterwards. Amounts are the one thing people say in English, so Vomo expects that inside a Twi sentence.

You don’t have to beat the clock

The session lasts twenty to thirty seconds. Vomo decides everything up front and then types faster than anyone can, so the timer stops being your problem.

What happens to your PIN

Real money moves the moment MTN accepts the PIN, and there is no undo. The rules around it are deliberate.

Confirmed on a real device
